Campagnolo Record EPS RD12-RE2EPS 11-Speed Rear Derailleur
Campagnolo is a premium road cycling brand with deep heritage, founded and based in Vicenza Italy. The meticulous production and end results of their groupset components are unmatched, and their hand-built wheels are some of the best in the industry. Carbon and Titanium is used in abundance for ultimate durability and the lowest weight possible.
As with the mechanical parts, the rear derailleur represents the pride and joy of the EPS project and encompasses a series of technologies and innovations that allow shifting speed to be optimised and guarantee unprecedented precision, even in the case of multiple shifting with 11 sprockets at a time.
The EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor box and a sensor, the built-in resolver, that reads its movements.
The geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic parts.
The lower and upper bodies, the parallelogram and the carbon derailleur cage are moved by a screw system and lead worm screw (not a spring screw) which, in turn, is enabled by the electronic actuator that communicates with the DTI.The built-in resolver inside the actuator is capable of reading the movements of the rear derailleur at any time and optimising its position by communicating with the DTI (Digital Tech Intelligence).
